Except once again the manual is incomplete. You actually have to engage reverse, allow one beep at full volume, engage neutral, then quickly re-engage reverse to reduce the volume. Took two phone conversations and two dealer visits to find someone who was adequately trained in that voodoo dance to teach me.To reduce the volume of the warning tone: engage reverse gear twice in quick succession.
I've tried to find mine and I don't see anything. I know I have one because it has stopped working. I've looked inside and outside for anything that might resemble a backup alarm but I couldn't find anything. I'm just too busy to get it in to the dealer to get it fixed.It sits inside the left rear pillar.
Ah okay, mine sits right about here. When the doors open the top of the bumper is accessible behind the hinge and you can see the alarm.I have the flip up tailgate. But still nothing is inside that pillar.
Guys, it's not hard. Seriously it's a 15 minute job. I suppose if you're not a mechanical type, maybe twice that. You need a t-40 bit, and a zip tie. Open the back drivers side door. Just below the hinge, behind the bumper cover is the horn.So was anyone able to disable the alarm without taking it to MB?
